摘要: SUMMARY A conservative local interface sharpening scheme has been developed for the constrained interpolation profile method with semi-Lagrangian scheme, because does not feature a mechanism to control thickness, thus causing an increase of numerical error advance time step. The proposed is based on level set by Olsson and Kreiss. However, their can cause excessive deformation free-surface in certain circumstances, we propose improvement developing technique. Several advection tests are presented assess correctness improved scheme. This followed validations dam-breaking flow rising bubble flows. mass fluid exactly conserved computed terminal velocity agrees well experiments compared other methods such as volume (VOF), front tracking method, method.
